SPECIFICATION forming part of Letters Patent No. 463,219, dated November 17, 1891..

Application filed November 25, 1890. Serial No. 372,559. (No model.)

To aZZ whom it may concern:

Be it known that I, KENTON C. Kunntna citizen of the United States, residing at Leb anon, in the county of Varren and State of Ohio, have invented certain new and useful Improvements in Grain-Binders; andI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates -to certain improvements in that class of grain-binders in which the grain is carried against a yielding compress-finger and formed into a gavel, which becoming of sufficient size causes said compress finger to yield, thus throwing the trip and setting the binder mechanism into mo tion, and has for its object the provision of a simply constructed and efficient binder of the class above mentioned.

The invention consists in the construction and combination of parts hereinafter described, and pointed out in the claims.

hat I deem the best means for carrying the invention into practice is illustrated in the accompanying drawings, in which the several parts are referred to by letter, to enable me to explain the principles employed in my invention, and also in which 1 have shown so much of a grain-binder as is necessary to fully illustrate the several features of my invention.

In the drawings, Figure 1 is a plan view of my device. Fig. 2 is a transverse section taken at the lower end of Fig. 1. Fig. 3 is a transverse section on the line as 01;, Fig. 1,1001;- ing in the direction of the arrow. Fig. 4c is a transverse section on line y y, Fig. 1, looking in the direction of the arrow. Fig. 5 is a detail plan View of eccentric and co-operating parts. Fig. 6 is an elevation of the end gear. Fig. 7 is an elevation of a bolt for securing tl1epacker-arm to the spiders. Fig. 8 is a perspective view of the compressor base and bracket on which it is supported broken off from the machine. Fig. 9 is a sectional elevation showing the needle and compressor at the moment the dog comes into engagement with the ratchet when the forward movement of the needle is to be begun. Fig. 10 is a view similar to Fig. 9, showing the needle par tially elevated and the compressor at the point Where its inward movement begins. Fig. 11 is an edge view of the link connecting the crank on the needle-shaft and the compressorplate. Fig. 12 is a perspective view of a packer-hook detached. Fig. 13 is a similar view'to Figs. 9 and 10, taken at the moment when the bundle is under great-est compression. Fig. 14 is a view showing the construction of the compressor and needle-arm just after the opening or return movement of the needle-arm begins. Fig. 15 is a view similarto Figs. 9, 10, and 13, showing theposition of the parts when the compressor has dropped. Fig. 16 is a view similar to Fig. 15, showing the position of the parts just before the needle reaches its farthest rearward movement and when the pin on the compressor-plate is engaged and held under the lip-pawl and just priorto assuming the position for filling shown in Fig. 9,

In the several views of the drawings similar parts are designated by the same letter of reference.

A A are the frame-bars for securing the binder to the harvester, and ,2 z are crossbracesbetween the same, the center one .2 being extended as a bracket, as shown, to receive the compressor. .2 is a short brace secured to bars A, affording an additionalbearing for the needle-shaft and a bearing for the packer sh aft. The brace e is secured to brace the braces.

X is the main end casting, having at its upper end two parallel rods S S, said rods supporting at their outer ends a journal-bearing K, in which the corresponding portion of the knotter-shaft R rotates. It is evident that with very small additional weight there may be added several suitable braces, as shown at Y to the said. casting X, thereby greatly increasing its strength. Said main end casting is provided with two journalbearings for the purpose of suitably mounting the kuottershaft R, and the shaft T, extending from the e by a bar or rod .2 which stiffens and unites ICC packer device to the end gear, and also to said casting is rigidly secured in the proper place the journal-pin H, upon which the sway-bar L rocks.

R is the usual shaft upon which are mounted parts not shown, viz: sheaf-ejectors and knotter mechanism, all as usual; and T is the shaft extending from the packer system to the end gear and carries the eccentric \V, which actuates the needle A and upon which the clutch-pawl a a is mounted.

b b are cranks rigidly secured to the respective shafts R T. Uponthe wrists c and c of said cranks are respectively mounted the washers a 0L and the anti-friction rollers g 9 which travel reciprocatively through the respective slots q q, situated in either end of the swing-bar L. Said anti-friction rollers are sufficiently small to rotate upon the wrists c c as they bear against either side of said slots.

G is a pitman connecting the cranks b b and transmits the power alternately with the sway-bar L from the shaft T to the shaft R.

w 00' are spring-pins securing the anti-friction rollers and pitman to the wrists of the cranks, and 00 is a spring-pin securing the sway-bar to the journal-pin H. This mechanical movement is made the subject-matter of Patent No. 447,075, granted to me on the 24th day of February, 1891.

W is an eccentric securely mounted upon and carried by the shaft T. Said eccentric carries the pawls a a belonging to the trip mechanism,together with their spring g designed to throw the pawl a into engagement with the ratchet P, the part a of said pawl S is an arm of the trip-rod Y, passing through the slot 1) in the brace Z, in which it reciprocates and engages the pawl a to throw the pawl a from the ratchet P and disconnect thebinding mechanism, or releases by the action of the compressor-finger 0 said pawl a and permit the ratchet P to engage the pawl a and cause the binding mechanism to actuate. The outer end of said trip-rod Y is secured to the crank P which is rigidly secured to the rock-shaft U. On the opposite end of rockshaft U from the crank P is the armV, to engage the stud d, whichis rigidly secured to the link I. Said link I is so connected to the compressor-finger O that sufficient pressure against said compressorfinger will cause the stud d to raise the arm V and rock the shaft U sufficiently to release ciprocate upon said stud 7c.

the pawl d and unlock the binder mecha-n The link Iis loosely secured to the lug ism. p on the needle by the wrist f and also connected in a like manner to the compressorbar K by the wrist f causing the compressorfinger O as the needle rises to first recede from the gavel and then move toward said gavel or needle and compress the sheaf as it is bound, and in so doing places itself in such a position as to cause the said compressorfinger to fall sufficiently low as to allow the sheaf to be discharged and then to return to its position to receive the next following gavel, all of which is hereinafter fully explained.

The compressor-bar K to which the finger O is secured by the bolt t, is provided with the holes 1' r to allow for different sizes of sheaves and with the sloth, by which it is mounted upon the stud 70, provided with the nut Z to secure said vcompressor-bar thereto and allowing said bar K to both rock and re- The compressorbar is also provided with the pin m, upon which maybe mounted an anti-friction roller,

if so desired, said pin at being engaged by the cam-ledge it upon the main frame, the purpose of which is hereinafter explained.

On the outer edge of the bracket Z is loosely secured the lip-pawl a, provided with the spring I). Said lip-pawl is situated so as to engage the pin m and prevent the finger 0 from being thrown as the compressor recedes from the gavel, as hereinbefore referred to, as will be seen in Fig. 10; but after the finger O has been thrown in the manner spoken of and to he described the said lip-pawl a yields to the pressure of said pin mas it returns and allows said finger to pass to its former position, as will be readily seen in Fig. 16.

E is the usual shaft to which the power is applied from the harvester and which gives motion to the packer mechanism.

F F F F are eccentrically-mounted spiders rigidly secured to their respective shafts, and carry, in the manner illustrated, the packerhooks N. Said hooks are secured to the spiders by bolts e in such a inanner that the bolts 9 are rigidly fixed to arms of said spider and rotatably mounted in their respective journalbearings in said hooks.

Upon the inner end of the shaft E is rigidly secured the spider F, having to the outer end of each arm of said spider a bolt 0 securelyfixed, as before mentioned.

At sufficient distance to allow the packer= the center of the two spiders are apart. Said projection is constructed in such a manner as not to travel in the same plane as the body of the packer-hook N, and it will be readily seen that by this arrangement it is possible for the packer-hook to be much longer than if it and the projection traveled in the same plane. These projections extend from the body of the packer-hook at an angle somewhat greater than a right angle, experiments having proved that the best results are attained thereby. It is evident that by changing the center of either eccentric spider either up or down that any desired movement of the packenhooks may be obtained.

The entire packer mechanism consists of two such movements as the one just described, one mounted on each side of the needle. On the spider F which is loosely mounted on the inner end of shaft T, the ratchet P is securely fixed, by means of which the binder mechanism is actuated, as already explained.

By using the number of packer-hooks herein illustrated I am enabled to give the same speed to the packer-shaft as is given to the needle and knotter-shafts, giving as effective action upon the cut grain, and at the same time avoiding all complicated parts for changing the time from the packer-shaft to the needle and knotter shafts. I also avoid thrashing out the grain and breaking the straw, as it is evident that the faster the packer-hooks travel the greater is the force with which they beat against the grain, and it will be seen that the strain is taken from the needle-point in forcing its way through the tangled and clogged grain as the packer-hooks move with the needle and assist it in its efforts to part the grain.

The trip device herein described will set the binder mechanism into immediate action at the same moment that the gavel presses with sufficient power to throw the trip. This is not the case in binders heretoforemade; but, on the contrary, the packers of such binders often carry considerable grain into the gavel after the trip has been thrown and before the binder is set in motion, frequently causing the binder to become choked. The needle-shaft A* with its three bearings is very securely mounted and, as seen, is very short in length.

One of the novel features of my invention is throwing and raising the compressor-finger by the backward motion of the needle, which 7 is accomplished as follows: The slot h in the compressor-bar K causes the said bar to assume such a position with reference to the link I that as the needle returns the link I raises the inner end. of said compressor-bar, causing the finger O to be lowered sufficiently to allow the sheaf to pass out, and just before the needle has ceased its backward motion the stud cl on the inner side of link I is engaged by a suitable stop, preferably the arm V on the rock-shaft U, and changes the direction of power of the link I upon the eom- .pressor-bar in such a manneras to return the finger O to its former position, as will be understood from the views shown in Figs. 9, 10, 13, 14, 15, and 16. To fully insure the downward movement of the finger the forward end a of the cam-ledge n isso shaped and located as to engage the pin on and act as a starter. It is also evident that the sheaf will assist in throwing the finger 0 back sufficiently to allow it to pass out of the binder. It is also evident that the receding movement of the compressor-finger O is an advantage, as it allows the needle its full power to rise through the grain. Said finger does not move toward said needle until said needle has separated the grain and has full power to compress the grain against it.

It will be noticed that the weighty portion of the mechanism is located near the center of the binder instead of at one end, as is commonly the case, so that in shifting or adjustweight 011 the end of the tongue of the harvester will be unchanged.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a grain-binder, packer-hooks N, having projections N offset therefrom, so as not to travel in the same plane with the body of the packers, in combination with spiders on which the packers are mounted, as and for the purpose set forth.
